CALENDAR'.

Specification of Letters Patent.

Patented Aug. 28, 1906.

Application filed November 25, 1905. Seria! No. 288.996.

T0 all rtf/wm, t Tit/tlf concern:

Be it known that I, HENRY F. CUMMINGS, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain. new and useful Improvements in Calendars, of which the followin is a specification.

My invention re ates to improvements in calendars; and my object is to arrange annual calendars in such a manner that any date of the current year for which the calendaris published can be readily ascertained.

In order that the invention may he under stood, reference will now be made to the ac- -companying drawings, in whichww Figure l represents a front elevation of the improved calendar. Fig. 2 is a front elevation of one of the leaves detached therefrom.

A calendar arranged in accordance with my invention contains twelve leaves l, correspondingt to the number of months in a year and preferably secured., by means of staples 2, to a cardboard 3. The front page of each leaf is divided by vertical lines 4 into seven columns 5, containing numerals indi eating the days of the month, which numerals when read from left to right indicate the days of the week and when read downwardlyY the Sundays of the current year for which the calendar is published. The upper portion of each front page is divided into three rows 6, 7, and 8, the first of which contains the printed name 6a of the month and numerals 6b, designating the current year. The second row contains printed names of the days of the week. The third row contains a repetition of the words Sundays in and also the printed names of the months of the current year, said names being located in or over the columns containing the numerals designating the dates of the Sundays occurring in all of said months. For instance, as the Sunda 's occurring in the months of .April and Ju y fall on the second, ninth, sixteenth, twenty-third, and thirtieth days of said months the names of the latter will be placed in the second column 5 on the page containing January and in the fifth column 5 upon the page containing February, te., the names of the various months being placed in the columns containing the dates of the Sun days occurring in said months.

By examining Fig. 1 of the drawings it will be found that the Sundays occurring in J anuary and October fall upon the same dates.

Hence any date in October may be readily ascertained byeither adding to or subtracting from the numerals indicating said Sundays. Y As the months of January, April, July, September` October, and December contain five Sundays each, it will be necessary to supply each printed page with thirty-one dates, notwithstanding that the other six months contain less than said number of days. This is necessary to enable one to lind all of the dates of the Sundays occurring in the months above enumerated by simply referring to any of the printed pages.. For instance, if the current month be February it will not be necessary to turn the leaves to the one containing the month of December in order to ascertain upon what dates the Sundays of the latter month will fall, as this information is contained in the sixth column 5 of the page containing the month of February. By thus providing each leaf with thirty-one dates p laced in columns as described and arrangin the names of the months at the top of saifi columns in proper relation to said dates it is app arent that the date upon which any Sunday of the current year will fall can be readily ascertained by referring to any one of the rinted pages. With this information at hand the date upon which any day of the year will fall may be ascertained by either adding to or subtracting from the date of the nearest Sunday.4 F or instance, if the current month be January, 1905, and it is desired to ascertain upon what day the third Friday in December of the current year will fall it is only necessary to locate the column containing the Sundays of December (which in this instance will be the third column) and deduct two from the 17 appearing in said. column, which of course will give December 15 as the proper date.

lVhile I have shown the dates upon which the Sundays occurring in the year of 1905 will fall, it is of course understood. that these dates will vary with the different years. Hence I do not limit myself to the exact dates shown7 but claim the arrangement whereby the date or name of any da occurring in the current year may be readi y ascertained.

Although it is more convenient to read the calendar when the names of the days and months are arranged. in rows, yet the results obtained by this arrangement may be had by printing this information in columns. When this is done, the numerals representing the IOO days of the month must be arranged to read downwardly instead of from left to right7 as in the present instance.

Having thus described my invention, what 1 desire to secure by Letters Patent ishr 1. A calendar Consisting of' a plurality of leaves suitably secured together, each leaf containing numerals designating the current year and the name of a month occurring in said year, columns of consecutive numerals upon eaeh leaf equal in number to the number of days in the longest month of the year, which numerals when read in one direction indicate the days of the months corresponding with the days of the week of said month, and when read in another direction the Sundays of the year, a row containing the names of the days of the week arranged in proper relation to said numerals, and another row in which is repeated the words "Sundays in and containing the names of the month of the current year, said names being arranged in proper relation to the columns containing the numerals indicating the Sundays of the year.

2. A Calendar consisting of a plurality of leaves suitably seeured together, each leaf i upon each leai bei' ol days 1n containing numerals designating the current year and the name of a month occurring in said "year, columns of consecutive numerals equal in number' to the numthe longest month ol the year, which numerals when read in one direction indicate the days of the month corresponding with. the days of the week of said month, and when read in another direction the Sundays of the year, a row containing the names of the days of' the week arranged in proper relation to said. numerals, another row in whieh is repeated the words Sundays in and eontaining the names of the months of the current year, said names being arranged in proper relation to the columns containing the numerals indicating the Sundays of the year,

` circles inelosing part of the last-mentioned numerals, and a key describing what said circles indicate.

In testimony whereoi` I ailix my signature in the presence of two witnesses.
